Generate hexahedral mesh
Can somebody please help me with the following. I have an axisymmetric flow that I need to model exiting a nozzle. I have created a 3D mesh. I extruded the nozzle exit boundary downstream to represent the external flow domain. How can I generate a hexahedral mesh from the 3D mesh? Please see attached images.
It seems they do not have standard hexehedral meshing model to tool. They have the trimmer but it produces, for me, a disarrayed set to meshes. :confused::mad:
I had to create a nice one in Gambit in order to import it to CCM+. Try that or use Star-CD.
Note that ANSYS, except ICEM hexa (you get this base on license type) does not also come with hexa mesh tools. Once, gambit becomes/is considered obsolete, one will have no choice but stick to the cost effective unstructured grids anyways.
Good meshing Pluto. Oh, and if you figure a way to do this, let me know.
thanks for the advice. unfortunately i dont have access to STAR-CD but only to STAR-Design. I have checked on STAR-Design and there is no feature to generate a hexahedral mesh. Its a bit unfortunate that STAR-CCM+ does not have a hexahedral volume meshing tool. for now i will have to continue with the cylindrical extruded mesh. if i figure anything out i'll get back to you
thanks for the help fnk382
just a comment to fnk382:
The Ansys meshing platform does have hex meshing capability.
perhaps you should look at the CAE Linux 2009 distro. There are a few freeware meshing tools included which might work for you.
